Everyone who is serious about their health and has the means should be invested in reverse osmosis filtration at home with KDF and carbon pre-filtration even if you have "good" water.

Drinking huge volumes of water on the order of a gallon per day is important for general health and water is the main way most people ingest carcinogens due to sheer volume.

You absolutely don’t need to drink a gallon of water a day under all circumstances. You also certainly don’t need an RO filter in most places. Tap water can be a great source of some minerals, depending on location and a little fluoride is great for your teeth.

What carcinogens are you worried about in average tap water?

I don't believe that is true, and excess water can be dangerous by causing hyponatremia.

Yeah nobody is getting hyponatremia from drinking a gallon of water over the course of a day. Especially if eating a typical American diet.
